Step 2 — Describe one registry name

fraggate_describe

Read-onlyIdempotent

Retrieve a single FragGate registry card by name or slug to inspect status, public ops, aliases, and engine digest. Use after listing software when you need card details without executing operations.

Instructions

Inspect one known FragGate card (live vs stub vs local_only, public ops, engine_digest). Not execute and not a digest-only proof. Use this when you already have a name or slug from fraggate_list or GET /v1/software. Do not use it for discovering the full registry, proving a digest, pulling a hub product card, or executing an op; use fraggate_list, fraggate_verify, runtime_pull, or fraggate_call instead. Missing both name and slug, or an unknown name, refuses FG-HALLUC-TOOL. Wipe/unlock on embryolock stay FG-STUB. AZChat is LIVE+bound (mesh default off; not AZMail). Pass name or slug — one is enough. Combined name/op forms such as foldlock/fold-preview are accepted. Returns one registry card (ops, stub_ops, digest, status, aliases).

Input Schema

TableJSON Schema

Name	Required	Description	Default
`name`	No	Optional registry display name (for example FoldLock, EmbryoLock, AZHub). Use name or slug — one is enough. Combined name/op forms such as foldlock/fold-preview are accepted by the door parser. Unknown names refuse FG-HALLUC-TOOL.
`slug`	No	Optional catalog slug (lowercase a-z0-9-, for example foldlock, embryolock, azhub). Alternative to name. Prefer the slug returned by fraggate_list or GET /v1/software.

Output Schema

TableJSON Schema

Name	Required	Description
`code`	No	FragGate or fabric code when present: FG-OK, FG-HALLUC-TOOL, FG-STUB, FG-LOCAL-ONLY, FG-UNKNOWN-OP, FG-GATE-REFUSE, FG-LAMB-REFUSE, or a module refuse such as MESH-* / AKM-*.
`door`	No	Door name. The public door is fraggate.
`ran_in`	No	Execution locale (for example aziel-runtime) when present.
`result`	No	FragGate body: ok, code, door, slug, op, engine_digest, ran_in, provenance, refusal, limitations, receipt, plus the engine result. Unknown names refuse FG-HALLUC-TOOL; stubs refuse FG-STUB.
`status`	No	HTTP-like status when present on wrappers (200 ok; 400+ error / refuse).
`display`	No	Human-facing envelope. Show title and summary, then take the next input.
`receipt`	No	Optional receipt, ledger tip, or TemporalLock/ForgeReceipts exit when the door stamped one.
`refusal`	No	Explicit refuse object, code, or message when the door or engine refused.
`engine_op`	No	Resolved engine op when present (often inside result).
`ledger_tip`	No	Ask/refuse ledger tip when the door stamped one.
`provenance`	No	Provenance / input packet when the pipeline attached one.
`session_id`	No	Raw session id when session plumbing was used. Hidden unless the user asked for the chain.
`engine_slug`	No	Resolved engine slug when present (often inside result).
`limitations`	No	Capability limitations or Remain-OFF notes when present.
`engine_digest`	No	64-hex engine_digest when a true in-process engine ran (often inside result).

A4.8/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds substantial value beyond that: the refusal code FG-HALLUC-TOOL on unknown/missing input, the FG-STUB classification for wipe/unlock on embryolock, and the LIVE+bound state of AZChat with mesh default off.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core purpose and the not-this routing, then constraints, then return shape. Dense but every sentence carries routing or behavioral information. Slightly overpacked with domain classification (embryolock, AZChat) that borders on noise for a generic agent, but none of it is filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Output schema exists so return values need not be re-explained, yet the description still names the card fields. Combined with the refusal semantics, the stub/live distinctions, and the name/slug equivalence, an agent has everything needed to invoke correctly or route elsewhere.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds a real semantic detail the schema does not carry as prominently: pass name OR slug, one is enough, and combined name/op forms like foldlock/fold-preview are parsed. It correctly avoids restating the enum-less parameter definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Inspect) and resource (one known FragGate card) with explicit scope (live vs stub vs local_only, public ops, engine_digest). Immediately distinguishes itself from siblings by naming exactly what it is not (not execute, not digest-only proof) and listing the four alternative tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit when-to-use ('when you already have a name or slug from fraggate_list or GET /v1/software') and explicit when-not with a named alternative for each excluded case (fraggate_list, fraggate_verify, runtime_pull, fraggate_call). Prerequisites and refusal behavior (FG-HALLUC-TOOL) are also stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
